Experience & Expertise

Known for his outstanding attention to detail Daniel is able to rapidly review voluminous materials and extract relevant information, ensuring that all pertinent issues are identified and addressed. This results in advice that covers all of the issues.

Prior to joining Moray & Agnew in 2018, Daniel worked on a range of personal injury matters with this career experience providing a strong grounding in medical negligence, general insurance, CTP and workers’ compensation claims.

Since joining Moray & Agnew Daniel has continued to work on claims across different categories and to deliver value adds in his area of special interest on ‘costs’.

Daniel is a frequent contributor to Moray & Agnew’s Motor Directions publication and has authored several case summaries published on motor vehicle decisions.

He also gives back to the profession in his role of ‘judge’ at the annual Law Society of Western Australia’s Mock Trial Competition, and as a member of the Law Society Council and Australian Insurance Law Association (WA) Committee.

Daniel’s strong focus on commerciality and practical management of claims results in timely settlements and the minimisation of unnecessary legal costs.

In recent years Daniel has been at the forefront of the relatively new area of cyber risk insurance, presenting at seminars and publishing a number of articles on key legislative developments. His work in this area includes authoring numerous articles on cyber risk, including on the introduction of Australia’s mandatory data breach reporting obligations (LexisNexis Inhouse Counsel, July 2017) and the EU General Data Protection Regulation (Brief, August 2018).


Daniel acted as Counsel for the defendant in the matter of Smith v Walsh [2020] WADC 60, on a taxation of costs. The matter is currently the subject of an appeal by the plaintiff. 


Daniel was recognised as an Insurance Rising Star in the Doyle’s Guide for 2020.
